Application: January 17, 1983; SenialzNo;v 653,2 4]? 2 Claims. (01. 304-2 1) This; invention: relatesrxto improvements in safety seats for useiin-washing: windows from the outside, and its" leading: obj set. is to provide a seat which-can be positioned: onthe ledge-of a window opening andv held place by'supports which have a safe bearing against the inside of the room wall, so that outward movement. of the seat, while. it is supportingta person sitting thereon, will be effectively prevented;

Another object of theinvention is. theprovision of a safety seat for washing windows, which: can be adjusted to fit various shaped window openings.

folding. back rest, whereby outward movement of" the body of the person engaged. in washing the windows. will be positively prevented.

A still further object of the invention is the provision ofia safety'seat for windows having folding wall supports, meansfor adjustabl'y an? choring the body of the seat to theinner' edge of.

the window ledge, and a. folding back rest, all so arrangedthat the" device'can bestored in. a small space in a'compact condition; when nctin use;

With the above and other objects in View the' invention consistsin certain newan'd useful constructions, combinations, and arrangements of parts, clearly describe'et in' the following specification, and-fully illustrated in the accompanying drawing, in which:--

Fig, 1 is a plan view of the device, showing the foldable bracket arms in their extended positions.

Fig. 2 is a vertical transverse sectional view, taken on line 2-2 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a. vertical sectional view, taken on line 33 of Fig. 1, looking in the direction of the arrows.

Fig. 4 is a detail sectional view taken on line 4-4 of Fig. 1, looking in the direction of the arrow.

Fig. 5 is a fragmentary sectional view of one of the bracket arms.

It is the common and necessary practice of housewives to clean the outer faces of the window glass-panels, by first sitting on the ledge of the-window opening, and then moving the upper and lower window sashes-into cleaning position. In: this operation the cleaner usually permits her legs todrop against the inner face ofthe building wall, on the room side of it. This position is very uncomfortable, and at the sameti'me very dangerous. If the cleaner loses her balance; es= pecially' when the window sash is not pressing against her legsgshe islikely to ran entirely from the windowledge and become seriously injured or be actually killed.

The-objector the present invention is to pro' vide a window seat which will be comfortable; which can be attached place'by any womanor otherr person, without" skill, and which willaiford a seat of positive security and. safety at all times to the personcleaning the window. Should-=- it be difficult for aiperso'n so seat'edupon-3 myimproved window seatto raise a lowered win dew, she or he would be perfectly safe against nervous collapse, or other Referring to the accompanying drawing illus-- trati'ng the" practical construction of the iii-yen tion, 5: designates thebo'd'y of the window seat; which is shown in the fer-m of a flat piece of wood or similar materiali Against the underside of this wood-or material one ormore leveling locks Wis-secured, for the purpose of engaging the depression which normally" exists on-' window ledges. The bottom face on faces of this block or blocks isprovi'ded with a facingo'f'rubher 81rso that any wood or other finishupon the" ledge will-not be injured.

Upon this flat board aplate 1 is mounted to slide against the right edge of the hoard-and a' similar plate) 831s mounted to slide" against' the left edge of the board. The plate is formed with a longitudinal slot la, and may be formed with transverse corrugations lb, which are located in the sides of the slot. This plate may also have an upstanding reinforcing flange or rib Tc.

The plate 8 is of similar construction, and is provided with a slot 80., the sides of which are corrugated at 8b. This plate is also formed with an This bar plate is approximately the width of the board 5, forms the body of the seat.

The plate I is formed with an outwardly extended corner portion l0, which provides a U- shaped guiding joint for the folding bracket arm I I. This bracket arm is shown to be constructed of angle metal, but its inner end is formed to provide a hinge element II a, which works between the spaced jaws of the U-shaped guide Illa of the portion I0. A clamping screw l2 and a winged nut 13 is utilized for pivotally and adjustably holding the hinge element Ila of the folding bracket arm in proper relation to the guide 1a. This hinge joint Ilia is disposed at a slightly rising angle so that the bracket arm will project upwardly. The inner flange H of the bracket arm is provided with a cloth facing ll so that it will not deface the finish of the wall with which it is engaged.

The plate 8 is also formed with an offset U- shaped hinge guide M which receives the inner flattened end of the folding angle bracket arm l5. A screw [6 pivotally connects the arm to the guide M and a winged nut I7 is threaded on this screw for adjustably holding the bracket arm in fixed position. The inner vertical flange l5 of the bracket arm I5 is provided with a cloth facing I5".

The plate bar 9 is formed with one or more hooked or curved flanges l8, which are adapted to engage the inner edge of the window ledge, which in most cases projects slightly into the room, so as to afford a good connection for the hooked flange l8. The inner face of this hooked flange is provided with a cloth facing i8, so that the finish of the window ledge will not be injured.

A screw I9 is extended through the inner vertical flange of each folding bracket arm, and the inner end of this screw is formed with an eye Na and the outer end is engaged by a winged nut 20, which has a thrust engagement with the inner vertical flange of the bracket arm. The eye of each screw is connected by the chain or flexible member 2| with the screw eye 22, flxed to the side of the seat board 5.

The plates 1 and 8 are adjusted on the seat board 5 by means of the screws 1s and 8s, which are flxed in the seat board, so the shanks of the screws project through the slots of the plates. These screws are engaged by the winged nuts Is and 8s, and between these winged nuts and the upper faces of the plates 1 and 8 the corrugated which sheet metal washers 1w and 8w are arranged,

for the purpose of preventing the plates 1 and 8 from slipping on the board.

The seat board 5 is also provided with a folding back rest 23, which is connected at its lower end by the hinges 24 to the seat board 5. In order to hold the seat rest in an upright position a strap 25, of flexible material, is extended across the back of the seat rest and then extended diagonally at its end portions and positively fixed to the side edges of the seat board forwardly of the transverse line of the hinge joint of the seat with the back rest. In this way a folding seat rest is provided and the diagonal side portions of the connecting strap form side guards for preventing the sidewise yielding of the body of the person cleaning the window. When it is desired to fold the seat rest all that is necessary to do is to swing it toward the seat board. The back rest serves to support a person cleaning windows, so that there is no possibility of the person falling backwards.

When a person wishes to clean a window, all that is necessary is that the seat board be placed in position on the window ledge, the hooked flange or stop engaged with the edge of this ledge, adjusting the side plates 1 and 8 on the seat board for this purpose. The bracket arms are opened outwardly in the meantime and then placed against the inner face of the room wall, in the relation shown in Fig. 1. 'The winged nuts 20 are then manipulated to tighten the chain connecting the bracket arms to the sides of the seat board, so as to rigidly support the seat board.

When thus secured in place the seat board cannot tilt upon the window ledge, and it ca'nhot shift outwardly on the window ledge, due to the depending and overlapping engagement with the inner edge of the window ledge and the resistance offered by the two connecting chains.

Having described my invention I claim:--

1. A safety window seat for cleaning windows consisting of a base board, side plates adjustably mounted on the base board, a cross bar connecting the plates to each other, the side plates having U-shaped hinge elements, folding bracket arms hinged to the hinge elements, a chain connecting each bracket to the base board, and means for adjusting the tension of each chain.

2. A safety window seat consisting of a base board, an adjustable depending flange on the base board, means for clamping the flange in various positions on the base board, a back rest folding on the base board, a flexible bracing mern-. her for the back rest, folding bracket arms hinged to the opposite sides of the baseboard, chains connected to the sides of the base board, screws carried by the bracket arms engaging the chains, nuts threaded on the screws and engaging the arms to adjust the tension of the chain, and a folding back rest on the base board.
